C++/Deque/deque insert
Insert elements in vector to deque
#include <iostream>
#include <deque>
#include <vector>
using namespace std;
int main()
{
int data[5] = { 6, 8, 7, 6, 5 };
vector<int> v(5, 6); //5 element vector
deque<int> d(data, data + 5);
deque<int>::iterator p;
cout << "\nDeque values" << endl;
for (p = d.begin(); p != d.end(); ++p)
cout << *p << "\t";
cout << endl;
d.insert(d.begin(), v.begin(), v.end());
for (p = d.begin(); p != d.end(); p++)
cout << *p << "\t";
}
Insert the remaining elements from the vector between the first and last deque elements
#include <iostream>
#include <deque>
#include <vector>
using namespace std;
const int SIZE = 100;
double sum(const deque<double> &dq)
{
deque<double>::const_iterator p;
double s = 0;
for (p=dq.begin(); p != dq.end(); ++p)
s += *p ;
return s;
}
int main()
{
vector<double> vec(SIZE, 0);
deque<double> deq;
int i;
double sumTotal;
for(i = 0; i < SIZE; i++){
vec[i] = i * 0.6; cout << vec[i] << endl;
}
deq.push_front(vec.front());
deq.push_back(vec.back());
deq.insert(deq.begin()+1, vec.begin()+1, vec.end()-1);
sumTotal = sum(deq);
cout << "sum:" << sumTotal;
}
